PORT HURON, Mich. -- Customs inspectors arrested the driver of a Canadian garbage truck Wednesday after they discovered 1 ton of marijuana concealed behind the trash he was transporting.

Inspectors at the Blue Water Bridge in Port Huron found the drugs after a gamma ray scanner showed anomalies in the truck's cargo, said Cherise Miles, a spokeswoman for U.S. Customs and Border Protection.

The scanner works by producing a picture, similar to an X-ray machine, of the truck's contents for inspectors to scrutinize, she said.

The truck was then sent for a secondary inspection.

"Upon opening the rear of the garbage truck, a plastic garbage bag filled with marijuana fell out," Miles said. (OOPS!)

An ensuing search revealed multiple plastic and hockey bags full of marijuana, which filled up most of the rear of the garbage truck, she said. (Bet this guy crapped his pants!!)

The driver of the truck, a 37-year-old man from India, was taken into custody and is expected to be charged with conspiracy to smuggle marijuana, Miles said.

According to the truck's manifest, it contained solid waste (well it's waste now! ) and was headed to a trash dump in Michigan. The location of the dump or origin of the trash was unknown, Miles said.

Wednesday's bust wasn't the first time drugs have been found in a garbage truck coming from Canada. In April, three people were arrested after a load of trash headed for a Wayne County landfill was used to bring 50 pounds of marijuana into the United States.

Lawmakers who want to halt the trash shipments, which are now up to 125 truckloads a day from Canada, have been outraged to learn some of the loads contained illegal drugs, medical waste and other hazardous material not allowed in Michigan landfills.

"A ton of marijuana in one truck!" state Rep. Kathleen Law, D-Gibraltar, exclaimed after being informed of the discovery.

"This just underscores that trash from Canada leaves us open to this kind of illegal activity. We must pass legislation and we must regulate the bridge.

"It's just out of control," she said. "This is scary."

Bills designed to halt or delay trash shipments have been introduced in Congress and the state Legislature.

In Prince Rupert, British Columbia, the U.S. consul general expressed his displeasure with the flow of marijuana from that province to the United States.

"We don't like it," Luis Arreaga said Wednesday. "Two to 3 billion dollars in marijuana goes south every year." (YEAH! How dare we take away Canadian business! )

U.S. government research shows a link between long-term brain damage and marijuana use, Arreaga said. The trade harms Canada as well, he said, because illegal guns and harder drugs flow back across the border in exchange for the marijuana.
